In the early 1920s, the physics department had been licensed under the call 9YAG. The club was founded by 1925 and was licensed under the call W9IU by 1930. Later, the club's call was changed to K9UAN, and in 1960 it moved to a shack at the [[Indiana Memorial Union]]. The club's current call sign, K9IU, was issued in 1962.
